The vehicle occupant restraint system development methods, including test methods, computer simulation analysis method. Test methods exist long development cycles, high costs, and can not be repeated shortcomings. As computer technology matures, the computer simulation analysis methods in the development of occupant restraint systems play an increasingly important role in the study are also increasingly using a combination of experiment and computer simulation method. MADYMO as an occupant injury evaluation software, is one of the commonly used software for automotive occupant restraint system simulation. Use of a MADYMO occupant restraint system optimization design, the need to design a good restraint system parameters combinations provided in MADYMO the calculation module XMADgic-7.1 calculation file modify, XMADgic-7.1 calculated, and wait for the calculation is finished, open many MADYMO post-processing files, to find the damage in various parts of the occupant response, and then manually copy find or input to be processed in the form, and its comprehensive evaluation. When these needs dozens or even hundreds of times repeated, manual labor becomes to optimize the work of the leading, and computing time need someone keeper, waiting for time after the completion of the operation, processing the data and then the next time computing, such not only error-prone, and can not improve efficiency. MADYMO occupant restraint system simulation and optimization, automatic cycle solver for XMADgic-7.1 as well as the results of rapid assessment procedures designed to XMADgic-7.1. First, to achieve the the editing saved parameter after the design constraint system parameter calculation file XMADgic-7.1, the automatic calculation of the driving XMADgic-7.10, and the calculation of all the combinations of parameters to achieve in the case of unattended; Secondly, complete simulation, batch extract occupant injury response data, and to evaluate the response of the crew according to different design objectives and requirements of the occupant restraint system, to select the optimal combination of parameters; Finally, the B301 occupant restraint system development, for example, briefly MADYMO modeling and verification process, and automatic cycle solver and rapid assessment procedures reflect its advantage in the development of their occupant restraint system of automatically solving calculated and occupant response evaluation, compared to traditional optimization methods. This paper explores the simulation process of the occupant restraint system, and asked the occupant restraint system quickly CAE method, design and development of the automatic cycle to solve for MADYMO rapid assessment procedures, the method can achieve rapid automatic XMADgic-7.1, XMADgic-7.1 occupant injury in response to the rapid extraction and rapid evaluation. In this paper, the use of these two procedures to achieve fast simulation and rapid evaluation of a vehicle occupant restraint system, to prove the usefulness of the method. In this paper, the occupant restraint system MADYMO Simulation Analysis of some reference value.
